Cosmetic and Skincare Formulation

A formula has to work three times: on the bench, in the package, and on production equipment. MakeMine develops to all three from the start — so the formula that tests well at 500 grams also runs at 500 kilograms.

The bench formula and the manufacturable formula are not the same thing

A chemist can make almost anything at bench scale. Two hundred grams in a beaker with a lab mixer tolerates viscosities, emulsions, and heat profiles that a production vessel will not. The formula gets approved, the brand falls in love with the texture, and then the scale-up trial fails — the emulsion breaks, or the fill head can't move it, or the batch takes nine hours of heating that nobody costed.

Now you're reformulating a product you already showed investors.

Formulation done properly targets the equipment, the cost, the claim, and the package at the same time — not the texture first and everything else afterward.

What formulation covers

Brief development

Target texture, claims, price per unit, volume, and regulatory pathway defined before bench work starts.

Benchmark analysis

Reference products deconstructed so the target is a specification rather than an adjective.

Bench development

Iterative formulation to the agreed target, with each round tied to a defined change.

Cost targeting

Formula cost per unit tracked through development, not discovered at quoting.

Claims support

Formula built to substantiate the claim you intend to make, with the testing that claim requires identified upfront.

Regulatory pathway

Cosmetic or OTC drug determined before development, since it changes the facility.

Scale-up and pilot batch

Trial production run confirming the formula performs on the actual equipment.

Technical documentation

Batch record, specification sheet, and INCI declaration.

How formulation runs

Typical duration
  1. Brief

    1–2 weeks

    Claims, texture, cost target, volume, and pathway agreed

  2. Bench round 1

    3–5 weeks

    First formulation submitted against the brief

  3. Bench rounds 2–4

    2–4 weeks per round

    Iteration on texture, scent, absorption, and cost

  4. Formula lock

    Final formula approved; specification sheet issued

  5. Stability initiation

    12 weeks minimum

    Testing starts immediately on lock — see Sampling

  6. Pilot batch

    3–5 weeks

    Scale-up trial on production equipment

Stability starts the day the formula locks. Every day between a "good enough" formula and a locked one is a day added to launch.

What a formulation brief must contain

A lab can start from less than this. It will cost more rounds.

ElementWhy it's required
Target claimsDetermines cosmetic vs. OTC pathway and what testing is needed
Benchmark productsConverts "lightweight and dewy" into a measurable target
Target cost per unitFormula cost is decided at development, not negotiated after
Target volumeBatch size drives which facility and which minimums apply
Package formatAirless pump, jar, tube, and dropper each constrain viscosity
Ingredient restrictionsFree-from lists, certification requirements, allergen exclusions
Fragrance directionScent development runs on its own timeline and can gate the schedule
Target marketsUS, EU, and other markets carry different ingredient restrictions
Shelf life targetDetermines preservative system and stability protocol
Launch dateDetermines whether custom formulation is even viable

Formulation timelines and typical development cost

Product typeTypical bench developmentNotes
Cleanser, toner, mist6–10 weeksSimpler systems, fewer stability variables
Serum, essence8–14 weeksActive stability is the main constraint
Cream, lotion, emulsion10–16 weeksEmulsion stability drives round count
Balm, oil, anhydrous6–12 weeksNo water phase, no preservative system
Haircare (shampoo, conditioner)10–16 weeksSensory and rinse performance require more rounds
OTC drug (SPF, acne, antiperspirant)16–28 weeksMonograph compliance and efficacy testing

What MakeMine will tell you in formulation

  • If your cost target and your ingredient list are incompatible, we tell you which one has to move before bench work starts.
  • If the claim you want requires clinical substantiation, you get that cost in the brief, not the invoice.
  • If your product is an OTC drug, we say so immediately. It changes the facility, the timeline, and the price.
  • If private label gets you 90% of the product at 20% of the timeline, we will tell you that even though it is the smaller engagement.

Frequently asked questions

How much does cosmetic formulation cost?

Custom formulation cost varies by complexity and by how many bench rounds the brief requires. Simple anhydrous products sit at the low end; emulsions, color matching, and OTC drug products at the high end. Cost is driven mainly by round count, which is driven by how specific the brief was at the start. MakeMine quotes development against your brief rather than a rate card, so the number moves with what the brief leaves open.

How long does it take to formulate a skincare product?

Bench development typically takes 6 to 16 weeks depending on the product type, followed by a minimum of 12 weeks of stability testing and a 3 to 5 week pilot batch. Serums and emulsions take longer than cleansers and balms because active and emulsion stability drive additional rounds.

Who owns the formula a contract manufacturer develops?

It depends entirely on the agreement, and it is the single most important term to settle before development starts. Some manufacturers retain ownership and grant exclusivity for a period; others transfer ownership outright. If ownership isn't addressed in writing before bench work begins, the default rarely favors the brand. MakeMine settles ownership in the manufacturing agreement before bench work starts, so you know which you have before you pay for development.

What is the difference between a formulator and a contract manufacturer?

A formulator develops the formula. A contract manufacturer produces it at scale. Some facilities do both; many do not. When they are separate, someone has to own the handoff — the scale-up trial, the equipment constraints, the batch record — and that gap is where most launch delays originate.

Can I formulate around a "free-from" list?

Yes, and it is common. Excluding preservative classes, silicones, sulfates, or specific actives is workable, but each exclusion narrows the available chemistry and can extend development. Preservative exclusions in particular require alternative systems that must be validated by preservative efficacy testing rather than assumed.

What is a pilot batch and why do I need one?

A pilot batch is a scale-up trial that produces the formula on production equipment before the full run. It confirms that mixing, heating, and filling behave as expected at production volume. Skipping it means the first time your formula meets real equipment is on a batch you've already paid for.
